ABSTRACT:
Exemplary embodiments of some aspects of the invention provide an optical decoding device including: a splitting device having first, second, and third, terminals; a nonlinear element; and an attenuator, wherein the second and third terminals are associated with an optical loop including the attenuator and the nonlinear element, the nonlinear element being displaced from a mid-point of the optical loop, and wherein the decoding device is able to receive multiple encoded signals via the first terminal, to decode at least one of the encoded signals and to provide a decoded signal at the first terminal in response to the at least one encoded signal. Exemplary embodiments of further aspects of the invention provide an optical code responsive device for decoding optical encoded signals, codes, and/or symbols, for header processing, for header reading, for address decoding and/or for optical packet routing.
